What is Constructor? Overview & background
Constructor is an AI-native e-commerce search, product discovery, and retail media platform built for VP of Digital Commerce leaders, head of merchandising teams, and retail media directors at enterprise retail brands. Founded in 2015 by Eli Finkelshteyn and Dan McCormick and headquartered in San Francisco, California, the company operates with 201 to 500 employees and has raised $86.1M in venture funding through Series B backed by Sapphire Ventures, Silversmith Capital Partners, Fusion Fund, Zetta Venture Partners, and SAP.iO. It replaces brittle keyword-matching search bars with a central Commerce Reasoning Engine that interprets shopper behavior, session context, and purchase intent across every digital touchpoint.
How Constructor works: architecture & workflow
At the technical core of Constructor is a central Commerce Reasoning Engine architecture that combines behavioral clickstream machine learning with transformer-based LLM reasoning inside a unified cloud discovery pipeline. Rather than optimizing merely for click-through rate or requiring manual synonym rules, the platform's ranking algorithm ingests live catalog attributes, inventory availability, profit margins, and individual shopper affinities to optimize directly for revenue per session. Its suite of Shopping Agents—including a conversational AI Shopping Agent and a Product Insights Agent—enables shoppers to ask natural-language questions and receive personalized product comparisons in real time. Developers integrate the workflow via headless REST APIs, SDKs, and pre-built e-commerce integration connectors under verified SOC 2 Type II, ISO 27001, GDPR, and HIPAA security controls.
